I like complaining every now and then and I guess today is one of those days.

Yesterday I was AGAIN facing the dreaded software update - need to reboot now or later. Now it's been the 3rd time in the last 2 weeks that I am facing this, Is this normal?

I understand that there are a couple of 10.0 CVEs affecting the Linux kernel so I am assuming that's the reason why behind all of the dynamic development lately but I would like to get a straight answer from the horse's mouth.

Is it normal that I need to reboot UM even more often than Windoze nowadays? I can barely achieve a 7 days uptime before that reboot prompt pops-up.

Typically you'll be prompted to reboot when a core component of the OS is updated, such as the kernel.

Kernel updates are security updates, so they need to be applied and as a result the system needs to be rebooted.

If that's really a problem for you, Canonical has started rolling out a dynamic kernel patching infrastructure very recently, you can register up to three machines (for free, more machines = paid service) with them and those machines will no longer need to reboot when a kernel patch is rolled out.
